In this paper, balanced two-stage residual networks (BTSRN) are proposed for single image super-resolution. The deep residual design with constrained depth achieves the optimal balance between the accuracy and the speed for super-resolving images. The experiments show that the balanced two-stage structure, together with our lightweight two-layer PConv residual block design, achieves very promising...
Chinese character culture is the ancients will be the experience of life, into words, language, vocabulary and other forms and content, and derived from calligraphy, seal and other traditional artistic expression, with the creation of ingenuity; and for Nushu such as the disappearance of the national language there is a lack of convenient and effective design conversion model.
We propose a randomized user-centric remote radio head (RRH) clustering (UCRC) scheme for cloud radio access network (C-RAN) with physical layer (PHY) caching. The randomized UCRC design is modeled as a multi-timescale non-convex problem to optimize the average weighted sum rate (WSR). We first decompose the problem into short-term precoding and medium-term UCRC subproblems. Then we propose a low...
Video logos can be considered as a form of visible watermark which is a trademark or symbol to declare the video copyright. However, in some cases, it will cause visual discomfort due to the presence of multiple logos overlapped directly or blended with another logo in videos. In this paper, we use an efficient gradient- based average approach to detect the logo firstly; then, the selected logo mask...
A novel algorithm is proposed for solving the overlapped marker matching issues and satisfying speed requirement in a 3D video motion capture system. Firstly, the mean markers' longitudinal coordination difference in two parallel cameras is calculated to reduce 3D matching error. Secondly, the epipolar geometry restriction is used to make the corresponding marker be restricted in a line. Finally,...
